Costeño Beach Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s break this down. We’ve got a long stretch ahead, but you’re gonna need some patience.

The whole 16-day window is all about one spot: Costeño Beach. The swell direction is a solid NE, which is exactly what this exposed break wants to see. But there’s a quiet start. The first couple of days offer some waves, but the quality is a bit average so I’d let those pass. The real action starts to build toward the back end of the first week and into the second.

We kick off on Friday, 31 July, with a 2.1m NE swell, but the wind is a cross-on from the E at 20 km/h, making things choppy. The combined energy is moderate (655). The water temp is a warm 28°, which is bang on average for the time of year – no surprises there. Saturday and Sunday stay small and messy, with swell dropping to 1.2m to 1.6m and light cross-onshore winds. Not a great start.

Now, Monday 3 August and Tuesday 4 August see the swell pulse back up to 1.8m to 1.9m, and we get a couple of glassy windows – Tuesday afternoon is looking cleaner with a 1.5m NE swell and glassy conditions (combined energy 299). That’s a nice little session for a beginner or a longboarder.

But the real standout is Wednesday 5 August. The morning comes in with a clean 2.0m NE swell, glassy, no wind at all, and the combined energy is strong (571). The conditions are described as “very good.” This is your best bet for the whole outlook. The NE direction is exactly what the break wants, and with zero wind, it’s going to be smooth and playful. A bit of a crowd is possible here, as it’s sometimes busy, but with that quality, it’s worth it.

Thursday 6 August holds similar quality – 2.0m NE swell, glassy in the morning (combined energy 519), and another very good session. After that, the swell builds significantly. Friday 7 August sees 2.3m to 2.4m NE swell, but the wind turns cross-on and onshore, making it choppy. The energy is strong (702-690), but the wind is a killer.

The second week from 8 August onward is all about size. The swell stays between 2.1m and 3.0m, with a period of 8 to 9 seconds. This is a moderate period swell, so it’s not the long, lined-up groundswell you’d want for a point break, but it’s got push. The combined energy values climb into the 800s and 900s, and even hit 1271 by 11 August and again on 15 August. That’s very strong wave energy.

However, for a beginner-friendly break like Costeño Beach, anything over 1.5m is getting challenging, and by the time we hit 2.5m and above, it’s only for experts. On 11 August afternoon, the swell hits 3.0m, and the data says it’s too big for this break. Same again on 15 August. The wind is also mostly cross-on or onshore during this period, with a few glassy moments but nothing consistent. The only real bright spot in the second week is Thursday 13 August morning – 1.9m NE swell, combined energy 554, and a gentle cross-on breeze that’s at least manageable. Not a standout, but the best of a mixed bag.

There’s a significant gap in quality from the first week’s peak. After Wednesday 5 August, the conditions deteriorate for a while. If you’re a beginner, stick to the first few days of August, especially the 5th and 6th. For the experts, the later big swells (11th and 15th) offer size, but the wind will be messy.

Signing off, Rusty.
